## Important Topics of NCERT Exemplar Class 6th Mathematics Solutions Chapter 5: Data Handling

Introduction to Data:

Data is a collection of numbers gathered to deliver some kind of information. Data is collected and organised for various applications in our day to day lives.

Recording Data:

Recording data in lists can be a tedious exercise and therefore, it is organised using various techniques such as arranging them in tabular form or using tally marks.

Organization of Data:

Data can be organised in tabular by mentioning the category in one column and marking consecutively while counting. For easier interpretation, the fifth mark in a group of five marks can be crossed. These are known as tally marks.

A Pictograph:

A pictograph is a representation of data in the form of pictures of the objects. It helps to answer questions on the data at a glance. Pictographs are used by dailies and magazines to make the data in their content attractive. Interpretation of pictographs can be learnt and done by regular practice.

To draw the pictographs, interesting and simple symbols can be used. For instance, one can use a line diagram of humans to represent the number of people in any data, similarly, other easy symbols can be drawn.

A Bar Graph:

When the data is large, the representation of data in pictographs can be time-consuming as well as complicated. Therefore we use bars of equal width with equal spacing between them. We draw these bars either horizontally or vertically. The length of these bars represents the desired data. This method of representation of data is known as a bar diagram or bar graph.

The bar graphs can be interpreted with the help of the scale that is used for plotting the graph. For instance, A unit of length of the bar might represent 5 apples from a set of data, therefore 2 units will represent 10 apples and so on. We can adjust the scale in accordance with the quantity of data.

For drawing a bar graph you may follow the following steps:

1. Firstly we designate the horizontal and vertical axes as per the requirement of the data.
2. Next, we choose a desirable scale so that the bars can accommodate the given data.
3. Now we can draw the length of the equidistant bars according to the scale chosen.

Bar Graphs are used in our daily life for a variety of applications such as to compare things between different groups or change in data with respect to time etc.
